Matlab Ode Solver for Kinetic Modelling and Simulation of Claus Process Reactions
Keywords:
Clauss process, Acid gas treatment, Kinetic modellingAbstract
This paper is focused on a kinetic study and parameter analysis of a chemical reactions in a Claus process of a sulphur recovery unit at Mellita Gas plant. The chemical reactions that take place either in H2S conversion furnace or in a catalytic converters are studied by an analysis procedures that linked a kinetic modelling to a reactors performance. The kinetic data of a chemical reactions in a Clauss process were achieved a ProMax (software) simulator. A PROMAX process simulator is installed and connected to a Distribution Control System (DCS) through instrument analysers and transmitters of a Claus process in a sulphur recovery unit at Mellita Gas plant. A plant kinetic data were used to estimate a reactions parameters by a MATLAB code apply a nonlinear curve fitting regression. The developed kinetic model for a multiple reactions that appear in a several differential equations was implemented and solved numerically by ODE45 solver that available in a MATLAB library. The kinetic model results were visualized and displayed graphically by a MATLAB plot functions.
